I don't have enough context to determine exactly who 'garp' is. It could be a newly created character by the fanfic writer, or it might be a character from a relatively unknown story that is being incorporated into the 'ace fanfic'.
One possible love story for Monkey D Luffy could be with a girl he meets on an island. Let's call her Nami. Luffy, with his big heart and carefree nature, starts to have a special bond with Nami. He doesn't understand it as a traditional kind of love at first. But as they sail together, he always makes sure Nami is safe and happy. He shares his food with her, and when she's in trouble, he's the first one to jump in and protect her. Slowly, Nami also realizes how much Luffy means to her, and they develop a deep, unspoken love.
One great Monkey D. Dragon fanfiction is 'The Legacy of Dragon'. It delves into his past and how he became such an important figure. Another is 'Dragon's Path', which focuses on his journey and the challenges he faced. 'Meeting with the Unknown' is also popular, where Dragon encounters strange new allies and enemies.
One possibility in this fanfiction could be that Naruto gains new and unique combat skills. Monkey D. Dragon is known for his revolutionary ideas and powerful abilities in the 'One Piece' world. Under his training, Naruto might learn different ways of strategizing and approaching battles, perhaps incorporating some of the more unorthodox fighting styles from the 'One Piece' universe. This could lead to Naruto becoming even more formidable, not just in terms of his ninjutsu, but also in his ability to lead and inspire others in a different way, much like how Dragon has an impact on the 'One Piece' world.
Well, you can start by looking on Reddit. There are some dedicated subreddits where fans share and discuss their favorite Monkey D. Dragon fanfictions. Additionally, some anime - related forums also have sections for fanfiction. For example, the One Piece forums might have some great stories about Dragon since he is from the One Piece universe.
A Monkey D Luffy love story could be about him falling for a fellow pirate. They share the same love for the sea, adventure, and freedom. They might meet during a battle against a common enemy. Luffy is drawn to her fearless attitude and she to his leadership. They start to have feelings for each other as they sail across the Grand Line, exploring new islands and facing new challenges together.
One common theme is the exploration of gender roles. Since Luffy is typically male in the original, making her female in fanfiction allows writers to play with how she might break or conform to traditional gender roles in the pirate world. For example, she might still be as fearless and strong - but society in the One Piece world might react differently to a female pirate captain.
